About

I started out wanting to be an oceanographer. I get horribly seasick, it turns out, so I switched direction and pursued a doctorate in biophysical chemistry. I did a brief stint in neuroscience and then went to Berkeley for a post-doc in molecular biology. I loved bench science but the academic life was not for me. I didn’t want to get relegated to the “mommy track” although I wanted and did have kids. Shortly after returning form Berkeley I gave up academia to write science books for kids.

For over two decades, I have been exploring ways students learn. I started out as a research scientist in the field of biophysical chemistry but later left academia to work on writing better science books for kids, especially in the elementary grades. I started Gravitas Publications Inc. in 2003 and introduced the Real Science-4-Kids product line for home and classroom educators to provide informative, activity-based science curricula for kids K-8. Real Science-4-Kids gives students the basic building blocks for a solid science foundation.

After creating more than 100 textbooks, workbooks, teacher’s manuals, and leveled readers, I felt like something was still missing. Although the Real Science-4-Kids curriculum is a logically sequenced content-centered program, I wanted to capture the excitement I felt asking my own questions and making my own discoveries as a graduate student. I wanted to understand how learning happens and put that process in an easy to use box for kids.

To unpack my own learning process, I bought a one-wheel and taught myself how to ride it and in 2020, I decided to launch RATATAZ as a way to not only introduce fundamental science concepts but help students learn how to learn. The ability to confidently and independently learn anything is the biggest gift we can give our children. Before high school, standard science education usually covers only biology and earth & space science with little or no chemistry or physics, creating an early gap that can be difficult to overcome.

RATATAZ is a learning method that introduces the core STEM subject such as Physics, Chemistry, Biology, Geology, and Astronomy and nurtures kids’ incredible capacity for learning advanced concepts. All of the materials are included and all you have to do is just add water!

And there is always more to do and that’s the point of this site. Learning isn’t just about the best books (although the best books help), and it isn’t just about doing great experiments (although great experiments help). Learning is really about helping students take responsibility for their own learning and teaching them how to do that.
